Application filed January 15, 1906. Serial No. 296,014.

To all whom it minty concern:

Be it known that I, WALTER H. LUrz, a citizen of the Republic of Switzerland, residing at Knoxville, in the county of Knox and State of Tennessee, have invented a new and useful Improvement in Stoves, of which the followin is a specification, reference being had to the accompanying drawings.

My improvement relates particularly to ovens to which heat is im arted by the passage of products of com ustion or heated gases through the oven chamber.

My improved oven is adapted for heating various articles, and for adaptation to articles of different sizes the oven may be manufactnred in different sizes.

The drawings forming a part of this application illustrate my improvement in the form of an oven designed especially for heatin fiat-irons.

e object of the invention is to roduce an oven of such construction as wil permit economy in manufacture and at the same time afford efficiency and durability.

In the accompanying drawings, Figure 1 is a sectional front elevation of the oven. Fig. 2 is a sectional elevation of the right-hand side of the oven. Fig. 3 is a horizontal section on the line 3 3 of Fig. 1. Fig. 4. is a plan of one of the shelves removed from the oven. Fi 5 is an end elevation of said shelf.

in the form shown in the drawings the oven is rectangular in horizontal cross-section, there being two side Walls 1 1, a rear wall 2, and a front Wall 3. The drawings show the walls converging from the bottom upward; but they may obviousl be parallel. In the present case they are ma e converging to make the compartments of different sizes to conform to the sizes of a set of three flatirons. The side and rear walls are preferably integral, as shown by the drawings; but they may be made separately and suitably joined along their meetin edges. The front wall is formed so arate y from the other walls and is secure to the front edges of the side walls by the mechanism employed to him e the doors, as will be hereinafter descri (1.

Shelves 4 4. are used to support the flatiro-ns or other articles to be heated. Said Shelves are large enough to extend against the walls 1, 2, and 3 and have each a central o gening 5 and have upon their upper surface r1 slfi to raise the flat-irons above the shelf to permit the assage of products of combustion or other eated gases through the 0 ening 5 and between the flat-iron and the s elf. Said shelves rest on rear Lu s 7, extending horizontally forward from tie rear wall 2, and front lugs 8, extending horizontally rearward from the front wall 3. Said lugs are preferably placed near the side walls in order that the shelves may be su ported at or near the corners. Merely for t 1e pur )ose of supporting the shelves said lugs might be placed upon the side walls; but by placing them upon the rear and front Walls, as described, the parts are adapted for easy and economical casting. The side walls 1 and the rear wall 2 may be into ral, yet cast from a single pattern without t e use of cores, and the rent wall may also be cast in a simple mold without the use of cores, and the cars 10, hereinafter described, are so formed on the side walls 1 as to facilitate drawing from the sand.

It will be observed that the uppermost shelf constitutes the top of the oven. This is preferably placed at such elevation as to bring the upper edges of the ribs 6 to a level with the upper edges of the walls 1, 2, and 3 in order that said edges may assist in holding the article set upon the oven. Said shelf may also be used for heating a flat-iron5 but the iron placed thereon will not be so completely surrounded by heat as is the case in the compartments between the shelves. Op-

osite each compartment or space between the shelves 4 the front wall 3 has an opening 9 for the introduction .and removal of the articles to be heated in said compartments. Ap roximately opposite the lower. ortion of eac of said openings each side Will l 1 is provided with an car 10, extending horizontally forward through a slot 1 1 in the front wall 3. Between each pair of horizontally opposite cars 10 is placed a door 12 of proper size and form to rest flatwise against the front wall and extend u ward over the opening 9, locatcd next a ovc said pair of cars. Each such door has cars 13 adjacent the cars 10 and extending forward (when the door is closed) from the door. A shaft 14 extends through apertures 10 in the cars 10 and apertures 13 in the ears 13 and forms a hinge for .the door, and said hinge is forward of the door when the latter is in the closed position, so that the door tends to fall rearward by its weight, and thus bear against the front wall and need no latch. or other device for holding it in the closed position.

At the outer side of each car 10 (the side opposite the ear 13) is a lug 15, extending forward from the edge of the front wall 3 against the shaft 14. By means of the engagement thus formed between said shaft and said lug the said walls and. the front wall are firmly bound to each other, and this is the only means needed for holding together the va rious parts of the oven. In assembling the parts the shelves 4 are put into position. Then the front wall 3 is put into position, the cars 10 going through the slots 11 and the front lugs 8 slipping beneath said shelves. Then the doors 12 are put into osition and the shafts 14 pressed through t e apertures 10 and 13.

To adapt the doors to stand in the horizon tal position after they have been opened, each car 13 is provided with a heel 13 of proper form to bear against the outer face of the front wall 3 when the door is in the horizontal position. To more effectually close the joints formed between the meeting edges of the side walls and the front wall against the passage of gases, a rearward-directed Ii 16 may be formed along each lateral edge 0 the front wall, so as to extend partially over the outer face of the adjacent side wall.

As thus described the oven is complete and ready to be used for the heating of flat-irons or similar articles. The oven may be placed over one of the burners of a gas-stove, or the heated products of combustion or other heated gases may in any other manner be made to pass upward through said oven.

11 the form shown in the drawings the spaces between the shelves 4 are so low as to admit only the body of a flat-iron having a removable handle. For the introduction and removal of such an iron the iron may rest upon the open door while the handle is bein removed or attached, and it will be observe that the entire oven may be made without machine-work other than the drillin of the apertures 10 and 13 to receive the s aft 14. Even the shaft 14 needs no machine-work, for the apertures 10 and 13 may be of proper diameter to receive a shaft cut from wire of stock size. The walls, shelves, and doors may be formed of sheet metal instead of cast metal.
